Upright it's the same width, but reclined it is wider - going from 19 inches up to 32 inches because of the side arms reclining (although, admittedly, I can't recall what currently happens with the arms in First).

Not sure I like. The window looks like a gimmick and the cabin appears very stark, more so than Club. Like the additional width when sleeping (current arm rests are fixed) though I hope the armrest recline isn't linked to the seat recline as it is with NGCW.

I'll have a thorough poke around in March (or earlier if the op-up gods smile on me).
